- T 0. all whom it may concern:

Be-it l nown that l, THOMAS {-r. lVlnLisn, a citizen of; the UnitedStates of America, and aresident of 'incinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in 1 1 1 P I. Wire Structures, of whicn the renewing 1s aspecification.

illgis invention relates to wire sti'uctures and niliregspgciailrtothose used in the couitructioyl and manufacture ofrat-traps, grading screens for sand and the like, and its object is toprovidesstrong. and durable rib or tie-bar that is adapted to beinterlocked with and engaged by mesh-wires in silently and effectivemanner, a series of such ribs or tie-bars being used in parallel arrayalong the wire-mesh, transverse to the latter and holding them asuitable distance apart free from any possiblelateral play ordisengagementattheseveralintersections.

'ihe invention consists in certain novel features of the construction,combination and arrangement of the several parts of the improvedWire-structure, whereby certain important advantages are att ained andthe de vice is made simpler, cheaper and otherwise better adapted andmore convenient for ap .plication and use in rat-t-rap, sand-screen andsimilar structures, all as will be hereinafter fully set forth.

The novel features of the inventionwill be carefully defined in theclaim.

In the accompanying sheet of drawings illustrating my invention, i igure1 is a fragmentary plan view ofa wire-structure embodying my invention,showing such inven tion in a number of correlative forms; Iig.

transverse section of the rib or tie-bar shown both in Pig. 5 and at theextreme right in Fi 1, but with the two parts of the said rib shownapart and in position ready to be closed over a mesh-wire, the latternot being shown in this view; and big. 8, a fragmentary longitudinalcentral section of the rib or tie-bar seen in Fig. 7.

In these vievrs, 1 represents the ordinary mesh-sires, v: hich arearranged parallel to. each other andare preferably plain or unbent ones,but they are adapted to be bent at the desired points in rat-trap orsimilar structures and not necessarily bent at the intersections of thecross-ribs or tie-bars such as I use in my structure and which I v. illnow describe. Transverse ribs forming tie or bindingbars are provided,to suitably space and firmly hold the mesh-wires in suitable parallelpositio'n, duly'separated as customary in rat-trap and grading-screenstructure's. These ribs or tie-bars are of peculiar construction andform the essential feature of my invention herein. They are each com--posed of a pair of bars or dates formed of narrow strips of sheet-metathe mesh-wires being held between each air of saidstripsL Forconvenience, I wifldesignate 2 as the lower or base-plate and 3 as theupp er or clamping-plate of each. air of plates or strips forming theseveral ri s or tie-bars of my structure. These numerals, -2 and 3, areemployed in connection with each of the plates or strips forming theribs seen in Fig. 1 and 90 the following four views. A series of crimps4 s made In the several plates 2 and 3, of F1 '2, such crinips beingdisposed outwardly and or prongs made in the lower or base-plate 2,

alternating "with the transverse crimps 4, and 6 Indicates eachone of aseries of transverse slots provided in the upper plate or strip 3,

alternating with the crimps 4.in that strip, all as best seen in Fig.6.' When the two plates 2 and 3 are brought together for closing over aseries of transversely-disposed with the outer ends of said pro clenchedor bent down on the out.er .'nee-et--11o mesh-wires 1, the crimps 4coincide or registhe strip 3 so as to firmly unite the two strips 2 and3 together over the series of mesh- .wires.

. Each of the first five views of the sheet of drawings shows the mannerinwhich the tongues or prongs 5 are clenched and the two parts of eachof the ribs or tie-bars secured together with-the mesh-w ires heldbetween each pair of strips.

I-prefer the construction seen to the exf treme left in Fig. 1 and,also, shown in Fig.' 2

' bearing wires in the crimp-receptacles of Fig. 2 is obviated andespecially when the strips of sheet-metal are wide ones whereby a longeris provided for the mesh-' hes in the I tie-bars.

- in the fastening v In Fig. 3 I have shown crin1ps4 in the upper plate3 only, the lower plate 2 having no crim s therein, thus providing areceptacle for t eseveral mesh-w ires in said upper plate or strip only;'The crimps in this form must necessarily be deeper than those in eachplate of the form seen in Fig. 2, so that the lower structure comprisingsuitably spaced meshplate or strip 2 can be clamped contiguous to theupper plate and to the mesh-wires 1 of the two plates or strips 2 and 3over the said mesh-w ires.

In Fig. 4 I have shown the same deep crimps seen in Fig. 3, but thesecrimps are made in the lower plate 2 instead of in the upper one, andthe effect is practically the same as in the form seen in said Fig. 3.

I In. Fig. 5 I have shown a rib or tie-bar stru'cturefthat is extremelystiff and strong as a result of makmg the lower plate or strip 2 achanneled one, with upturned side edges or flanges 7, 7, such flangesbeing provided with vertical notches 8, the latter as best seen in Fig.8. 'lhe notches 8 form reoeptacles for the mesh-wires and take the placeof the crimps 4 seen in 4. 'lhe upper strip 3 is a plane'one in thisform, the same asgthat seen in Fig. 4 and the strips '2' and 3 have theprong and slot formations, 5 and 6, I respectively, the same as in theprevious views of the drawing, and said rongs are clenched 111 a likemanner. In ig. 8, however, I have shown that it is not necessary ribs ortie-bars if desired, especially if a very strong and rigidwire-structure 1s not required. 'I he upper plate3 in the form seen inFig. 3 is of the same width as the space between the flanges 7, 7 of thelower strip 2, so

that said upper plate can be brought withinthesaid flanges 7, 7 andclamped firmly in said Fig. 5.

It is obvious that instead of making elongated openings or slots in thetop plate or stri 3 and the broadtongues or project-ions in t e bottomstrip 2 of each rib or tie-bar, small circular openings could be made insaid upper strip 3' and narrow pins or tongues to corres 0nd tosuchsmall openings could be made in the lower strip 2 and a like lookingresult be effected, except that it would not be quite so stron I I claimAs a new article of manufacture, a wire wires and a series ofintersecting double strips of sheet-metal, such mesh-wires being helclat suitable intervals apart between said double strips, one of thestrips having a series of suitably spaced transverse slots and the otherstrip having a series of correspondingly spaced integral tongues adaptedto register wlt-h and engage said slots and clenched on the outerface'of the strip containing the slots for uniting the strips andclamping them firmly over and in suitable engagement with themesh-wires, and a series of transverse seats or depressions made in oneor both of sa1d double-strip members and ntervemng the respective slotsand tongues thereof.
